  Next, the ultraviolet light emitting unit 56 of the ultraviolet light emitting means 4 will be described mainly with reference to FIG. The plurality of ultraviolet light emitting units 56 have substantially the same configuration, and one of them will be described below. The illustrated ultraviolet light emitting unit 56 includes a unit housing 74. The unit housing 74 has an outer diameter that gradually decreases from the central portion in the longitudinal direction toward both ends.

A protection tube 62 is connected to both ends of the unit housing 74, and the electric cord 54 and the signal transmission cord 60 extending between adjacent ultraviolet light emitting units 56 are covered with the protection tube 62.

  The unit housing 74 is provided with a plurality of (for example, six) receiving recesses at intervals in the circumferential direction on one side (left in FIG. 4) and the other side (right in FIG. 4). An ultraviolet light emitting LED 76 is disposed in each housing recess. Each ultraviolet light emitting LED 76 is covered with a transparent protective lens 78, and the ultraviolet light from the ultraviolet light emitting LED 76 irradiates the ultraviolet curable tube 2 through the transparent protective lens 78 as described later.

The ultraviolet rays from 56 can be irradiated substantially uniformly over a relatively wide range.

  In this embodiment, as shown in FIGS. 2 and 3, a guide guide roller 80 is disposed at the front end portion of the storage chamber 8 of the insertion machine main body 10 (that is, in the vicinity of the guide opening 12). A pair of support arms 84 is fixed to the inner surface of the insertion machine main body 10 via a mounting shaft 82, and a guide guide roller 80 is rotatably mounted between the support arms 84 via a support shaft 86. Since it is configured in this way, the ultraviolet curable tube 2 and the ultraviolet light emitting means 4 are led out through the upper side of the lead-out guide roller 80 as described later.

  Further, a return wire 90 is further provided in association with the ultraviolet light emitting means 4. The return wire 90 is made of, for example, a metal wire, a rope, or the like, and its distal end side is connected to a connecting portion between the ultraviolet curable tube 2 and the ultraviolet light emitting means 4 or in the vicinity of the connecting portion, for example, connecting means 64. .

  A winding means 92 is attached to the outer surface of the rear wall 66 of the insertion machine main body 10. The winding means 92 includes an apparatus main body 94 attached to the rear wall 66, a winding roller 96 rotatably supported by the apparatus main body 94, and a handle 98 for rotating the winding roller 96. The rear end side of the return wire 90 is led to the outside through the lead-out member 100 provided on the rear wall 66 of the insertion machine main body 10 and then wound around the take-up roller 96 of the take-up means 92. Therefore, when the handle 98 is rotated in the winding direction, the return wire 90 is wound around the winding roller 96 and pulled by the return wire 90, and the ultraviolet light emitting means 4 is moved in the return direction.

  Next, a lining operation using the above-described lining apparatus will be described mainly with reference to FIGS. 5 to 9 together with FIGS. In order to line the existing pipe P, for example, as shown in FIG. 5, the ultraviolet curable tube 2 is accommodated in the front part of the accommodating chamber 8 of the reversing insertion machine 6, and the ultraviolet light emitting means 4 is accommodated in the rear part. To do. Then, the ultraviolet light emitting means 4 and the ultraviolet curable tube 2 are connected via the connecting means 64, and the ultraviolet light emitting means 4 is electrically connected to the connector 68.

  Next, the tube reversing insertion machine 6 containing the ultraviolet curable tube 2 and the ultraviolet light emitting means 4 is brought close to the starting side shaft 106, and the lead-out guide member 18 is connected to the distal end portion of the lead-out connecting member 16 of the reversal insertion machine 6; The ultraviolet curable tube 2 in the insertion machine main body 10 is pulled out through the lead-out connecting member 16 and the lead-out guide member 18, and its tip is inverted and attached to the annular mounting flange 20 (tube attachment process). In this way, the lead-out portion (that is, the lead-out connecting member 16 and the lead-out guide member 18) of the reversing insertion machine 6 extends downward in the starting shaft 106 and reverses the tip end portion (that is, the ultraviolet curable tube 2). The part attached in this manner is positioned so as to face the opening of the existing pipeline P.

  In such a state, the compressor 52 is operated to supply compressed air to the accommodation chamber 8 of the reverse insertion machine 6 through the air line 50 and the inflow pipe 48. Then, as shown in FIG. 5, the compressed air flows through the lead-out portion (the lead-out connecting member 16 and the lead-out guide member 18) of the reversing insertion machine 6 toward the tip, and the action of the compressed air causes the ultraviolet curable tube 2 to flow. Is pulled out from the tip side while being inverted, and the drawn-out portion 2a of the tube 2 is held in close contact with the inner peripheral surface of the existing pipe line (tube inversion derivation step).

  If the compressed air is continuously supplied from the compressor 52 in this way, the ultraviolet curable tube 2 is further pulled out by the action of the compressed air, as shown in FIG. The ultraviolet light emitting means 4 is pulled out through the lead-out part (the lead-out connecting member 16 and the lead-out guide member 18) of the reversing insertion machine 6 through 68, and this ultraviolet light emitting means 4 is installed from the departure side shaft 106 to the arrival side shaft 108. The pipe P is inserted and moved (reverse derivation / drawing step). Since the return wire 90 is also connected to the connecting means 68, the return wire 90 is also inserted and moved toward the arrival side shaft 108 as the ultraviolet light emitting means 4 is inserted and moved through the connecting means 68. .

  At the time of this insertion movement, the camera unit 58 disposed at one end of the ultraviolet light emitting means 4 moves behind the connecting means 64, so that the CCD image sensor (not shown) of the camera unit 58 is exposed to the ultraviolet light. The image information of the inner peripheral surface of the existing pipe line P to which the curable tube 2 is closely attached is acquired. Therefore, by viewing the image information from the image sensor, the state of the inner peripheral surface of the existing pipe line P, The adhesion state of the ultraviolet curable tube 2 to the existing pipeline P can be confirmed.

  When the other end reaches the arrival side shaft 108 through the existing pipe P while the ultraviolet curable tube 2 is reversed in this way, the state shown in FIG. 8 is obtained, and the above-described reversal derivation / drawing step is completed. In this state, the ultraviolet curable tube 2 is pulled out from the insertion machine main body 10, and the pulled-out portion 2 a has an inner circumference over the entire length of the existing pipe P that connects the starting side shaft 106 and the arrival side shaft 108. It will be in the state where it touched and covered the surface. The plurality of ultraviolet light emitting units 56 of the ultraviolet light emitting means 4 are arranged at predetermined intervals in the longitudinal direction over substantially the entire length of the existing pipe line P. In this way, the ultraviolet light emitting means 4 is brought into close contact with the existing pipeline P, that is, the inner peripheral surface of the existing pipeline P by introducing the ultraviolet curable tube 2 into the existing pipeline P while inverting the ultraviolet curable tube 2 using compressed air. The tube 2 can be positioned radially inside.

  Then, in such a state that the ultraviolet curable tube 2 is in close contact with the inner peripheral surface of the existing pipe P, power is supplied to the plurality of ultraviolet light emitting units 56 of the ultraviolet light emitting means 4 through the connector 68 to emit a plurality of ultraviolet light emission. The LED 76 is turned on (ultraviolet curing process). Thus, the ultraviolet curable tube 2 in which the plurality of ultraviolet light emitting LEDs 76 of the plurality of ultraviolet light emitting units 56 are in close contact with the inner peripheral surface of the existing pipe P is irradiated substantially uniformly in the circumferential direction and the length direction. The ultraviolet curable tube 2 is cured by the ultraviolet light emitted from the light emitting means 4, and thus the inner peripheral surface of the existing pipe line P can be lined as required. At the time of this ultraviolet irradiation, it is not necessary to move the ultraviolet light emitting means 4 in the longitudinal direction of the ultraviolet curable sleeve 2, and therefore it can be cured at a time with a relatively short irradiation time.

  After the ultraviolet curable tube 2 is cured with ultraviolet light, the light emission of the ultraviolet light emitting means 4 (that is, the plurality of ultraviolet light emitting LEDs 76) is stopped, and further, the supply of compressed air by the compressor 50 is stopped as shown in FIG. . Thereafter, a part of the ultraviolet curable tube 2 protruding into the arrival side shaft 108, a portion protruding from the existing pipe P and reaching the connecting means 64 is cut and removed, and the return wire 90 is pulled back in the removed state. That is, the handle 98 (see FIGS. 1 and 2) of the winding means 92 is rotated in the winding direction so that the return wire 90 is wound around the winding roller 98 and is pulled back to the departure side shaft 106 through the existing pipeline P. When wound up in this way, the ultraviolet light emitting means 4 is returned into the accommodating chamber 8 through the lead-out portion (the lead-out connection member 16 and the lead-out guide member 18) of the insertion machine main body 10.

  At the time of this pulling back, an image sensor (not shown) of the camera unit 58 in the ultraviolet light emitting means 4 acquires image information of the ultraviolet curable tube 2 (2a) lined on the inner peripheral surface of the existing pipe P. Therefore, by observing the image information from the image sensor, it is possible to confirm the lining state of the ultraviolet curable tube 2 to the existing pipeline P.

  In the above-described embodiment, the return movement of the ultraviolet light emitting means is manually performed. However, for example, the ultraviolet light emission means may be automatically returned and moved as shown in FIGS. 10 and 11, in this modification, a winding roller 122 is rotatably supported on the rear portion of the insertion machine body 10A of the reversing insertion machine 6A, and the ultraviolet light emitting means 4A is wound around the winding roller 122. The winding roller 122 is drivingly connected to a driving source 124 such as an electric motor. When the driving source 124 is driven in the winding direction, the ultraviolet light emitting means 4 is wound around the winding roller 122 as shown in FIG. Taken.

  The basic configuration of the illustrated ultraviolet light emitting means 4A is substantially the same as that of the above-described embodiment, and a plurality of ultraviolet light emitting units 56A arranged at intervals in the longitudinal direction, and these ultraviolet light emitting units 56A are electrically connected. The unit housing 74 of each ultraviolet light emitting unit 56A has a plurality of ultraviolet light emitting LEDs 76 arranged in two rows at intervals in the circumferential direction, and each ultraviolet light emitting LED 76 is a transparent protective lens. 78.

  A camera unit 58 is provided at the tip of the ultraviolet light emitting means 4A in the same manner as described above, and an image signal from an image sensor (not shown) of the camera unit 58 is passed through a signal transmission code 60 and image processing means (not shown).
